BRAKE- SHOE.

SPECIFICATION forming part of Letters Patent No. 702,890, dated June 17, 1902.

Application filed January 27,1902. Serial No. 91,375. (No model.)

To all whom it may concern:

Be it known that I, ALFRED L. STREETER, a citizen of the United States, and a resident of Ohicago, in the county of Cook and State of Illinois, have invented a Brake-Shoe, of which the following is a specification.

This invention relates to brake-shoes.

One object of the invention is to provide an attaching-eye for securing the brake-shoe in the brake-head which will not break off from the body of the shoe and allow the body of the shoe to fall.

A further object of the invention is to provide means, preferably in combination with my improved attaching-eye, for binding the body of the shoe together in order to prevent pieces of the shoe from falling in case the shoe breaks.

A brake-shoe of my invention consists of the various features, combinations of features, and details of construction hereinafter described and claimed. f

In the accompanying drawings a brake-shoe of my invention is fully illustrated.

Figure 1 is a top plan view of a brake-shoe of my invention in what I now consider its preferable form. Fig. 2 is a sectional view thereof on the line 2 2 of Fig. 1. Figs. 3, 6, and 8 are top plan views of three difierent modifications of a brake-shoe of myinvention. Fig. 7 is a sectional view of the shoe on line 7 7 of Fig. 6. Figs. 4, O, and 10 are sectional views on the lines 4 4, 9 9,'and 10 10 of Figs. 3, 6, and 8, respectively; and Fig. 5 is a transverse sectional view of another modification of a shoe of my invention.

Referring now to the drawings, 1 designates the body of the brake-shoe, consisting, as shown, of a single integral piece of metal. The form of brake-shoe illustrated, however, is purely conventional, and any other desired or approved form of brake-shoe may be substituted therefor.

The brake-shoe is adapted to be secured to the brake-head (not shown) by means of what may appropriately be called an attachingeye 2, consisting of a piece or pieces of strong tough wire which are upwardly bent or bowed at the middle of the shoe and are rigidly secured to the shoe, so as to form said attaching-eye in the manner desired, said upwardly bent or bowed wire or wires being preferably cast into the shoe.

In the preferable construction shown a lug 3 is formed on the shoe, adapted to engage the recess in the brake-head to prevent the shoe from shifting endwise. The lateral dimensions of the lug 3 will usually conform to established standards, but may be made of any desired shape and size.

In addition to its cheapness and strength an important advantage of the described construction is that the core for forming the hole or opening 4 through the attaching-eye 2 may be disposed within the lateral sides of the lug 3. Thus any fin formed at the edges of the core will not prevent the shoe from seating itself on the brake-head, Whereas .with the form of attaching-lug now in common use the core for the hole through said attaching-lug leaves a fin at the base of said lug, which necessitates dressing the back of the shoe in order that it may seat itself on the brake-head.

In what I now consider the preferable form of brake shoe embodying my invention (shown in Figs. 1 and 2 of the drawings) the attaching-eye 2 is formed by upwardly-bent intermediate portions of wires 5 and 6, the end portions of which extend longitudinally of and are rigidly secured to the body portion 1 of the brake-shoe. In the preferable construction shown also the end portions of said wires 5 and 6 are disposed adjacent to the back of said brake-shoe.

The wires 5 and 6 may be secured to the body of the brake-shoe in any suitable manner. As shown in said Figs. 1 and 2, the brake-shoe is provided with depressions 7 in its back, and said wires are secured to said shoe partly by being embedded therein and where they'are exposed, as in said depressions 7, by means of eyes or staples 8, secured in said brake'shoe through which said wires pass. Theextreme end portions 9 of said wires 5 and 6 are bent downwardly and are firmly embedded in the body portion of the shoe.

In the preferable construction shown portions 10 of said wires 5 and 6 extend above the back of the brake-shoe and are disposed so as to form the guide-lugs of the shoe,adapted to engage recesses in the brake-head and to secure said shoe against lateral displacement.

WVith a brake-shoe of the described construction it is obvious that the wires 5 and G,

being strong and tough and being firmly secured in the brake-shoe, will bind said shoe firmly together and in case the shoe should break would preventjpieoes thereof from falling. It is also obvious that the attaching-eye 2 may be made sufficiently strong to meet any possible requirements without exceeding neat and desirable proportions.

In the form of brake-shoe shown in Figs. 3 and 4 of the drawings the attaching-eye 2 consists of a simple staple, the ends of which are embedded in the shoe and are secured to rods or wires 11, which extend longitudinally the entire length of said shoe. As shown, said shoe has a flush back, and the wires 11 are entirely embedded therein.

In Fig. 5 of the drawings a brake-shoe is shown embodying my invention in a very simple form, the body portion lof the shoe consisting of an integral piece of metal and the attaching-eye 2 of a staple the ends of which are embedded in the body of said brakeshoe.

In the form of shoe illustrated in Figs. 6, 7, and 9 of the drawings a single wire 12 is secured to the shoe, preferably adjacent to the back thereof, either by being embedded therein by means of eyes or staples S secured therein or in other desired manner.

The attaching-eye 2 is formed bya loop 13, formed in said wire at right angles thereto, the lower portion of which is embedded in the body portion of the brake-shoe.

In the form of brake-shoe shown in Figs. 8 and 10 of the drawings two wires 14 and 15 extend the entire length of the brake-shoe, being preferably embedded in the beads 16, formed at the edges of the shoe by the depressions 7 in the back thereof. At the middle of the shoe the wires 14 and 15 are bent upwardly and across the shoe to form the attaching-eye 2. Opposite ends of said wires or rods will thus be on opposite sides of the shoe.

The word wire is used herein in a comprehensive sense and is intended to include any rod or rods, strips, forgings, or castings of strong tough metal secured to the shoe in the described manner to obtain the desired results.

I claim- 1. A brake-shoe comprising an attachingeye consisting of an upwardly bent or bowed wire or wires, thelower portions of which are rigidly secured to the body of saidbrake-shoe and a wire or wires which extend longitudinally of said brake shoe and are secured thereto, substantially as described.

2. Abrake-shoe comprising an attachingeye consisting of an upwardly bent or bowed wire or wires the lower portions of which are embedded in the body of the shoe and a wire or wires which extend longitudinally of said shoe and are secured thereto, substantially as described.

5. A brake-shoe comprising wires securedto the body of said shoe, portions of which are disposed so as to form the guide-lugs thereof, substantially as described.

6. A brake-shoe comprising awire or wires which extend longitudinally of said shoe and are upwardly bent or bowed at the middle of said shoe to form an attachingeye therefor, substantially as described.

7. A brake-shoe comprising wires which are upwardly bent or bowed at the middle of the shoe to form an attaching-eye and which comprise end portions which extend longitudinally of said brake-shoe in the same direction, substantially as described.

8. A brake-shoe comprising a body having integral retaining-lugs, and a wire attachingeye only parts of which are embedded in said lugs, substantially as described.

9. A brake-shoe comprising a body having integral retaining-lugs, and a wire attachingeye the bowed or upwardly-bent part of which is bare and the lower parts adjacent to said body are embedded in said lugs, substantially as described.

10. A brake-shoe comprising an attachingeye consisting of an upwardly bent or bowed wire or wires, a wire or wires which extend lengthwise of said shoe to which the attaching-eye is secured and a retaining-lug in which the portion of said attaching-eye adjacent to the body of the shoe is embedded, substantially as described.

11. A brake-shoe comprising an attachingeye consisting of an upwardly bent or bowed wire or wires the end portions of which extend lengthwise of the shoe and are secured thereto and a retaining-lug in which the portion of said attaching-eye adjacent to the body of the shoe is embedded, substantially as described.
